RAILWAY-RAIL JOINT.

To all 'whom 'it 'may concern;

Be it known that I, ROBERT S. DU Bosn, a citizen of the United States, residing at Odessa, in the county of Pasco and State of Florida, have invented certain new and useful improvements in Railway-Rail Joints, of which the following is a specification.

This invention relates to railway rails, and pertains especially to rail-joints of the class known as scarf joints.

The object of the invention is to provide a rail joint of such novel and peculiar construction, that the rail-ends may be expeditiously slid into each other, as they are placed upon the roadbed or ties.

further object of the invention is to provide rail-ends of such novel and peculiar construction, that they may be given an inclined sliding movement for wedging the end of one rail into the end of the next adjoining rail.

In view of the various rail joints having interlocking members and employing several bolts or equivalent devices for holding them together, it is my purpose to furnish a rail joint of simple, inexpensive and practical construction, necessitating but one fastening-bolt, and adapted to be slid vertically on inclined faces of the oining ends of the rails, whereby a line of rails maybe expeditiously joined together.

Other objects, advantages and improved results are attainable by reason of the special shape or construction of the rail-ends. for the purpose of interlocking them.

In the accompanying drawings forming partI of this application: Figure l is a side elevation of a pair of rails, partly broken away, embodying the invention. Fig. 2 is a similar view showing the joining ends of the rails in position to be slid one into the other. Figs. 3 and l are enlarged sections on the dotted lines -m and Q/-g/ respectively (Fig. l). Fig. 5 is a perspective view Fig. 6 is a rail.

The same reference numerals denote the same parts throughout the several views of the drawings.

The railway rails l may be of the usual construction except as to their joining ends, and the rails are spiked to ties 2 in the usual manner. The oining-ends of the rails l have the web thereof thickened at 3, so as to provide for the special shape and con- Speciiication of Letters Patent.

struction of said ends as will be hereinafter described.

The scarf end of the rail has an inclined face l extending from the tread or top of the rail to a point 5, whence a horizontal face 6 extends parallel with said rail top or tread to an inclined face 7 parallel with the face 4, the latter and the face 6 forming the front and bottom respectively of a scarf 8. The scarf 8 is projected or depends from the under side of the rail tread, and the face 7 extends upon each side of the scarf to a horizontal flange 9 on each side of the rail and parallel with the rail tread; and with the aforesaid faces et and (3 forms a diamond shaped scarf. The scarf is wedge-shaped in cross section, so that it increases in thickness from the rail to the faces 4t and 6, as clearly shown in Fig. 6 of the drawing. The scarf is tapered from its front end to its rear end, so that it diminishes in thickness throughout its width from the front end to the rear end thereof, and is provided with a central slot 9, for a bolt 10.

The socket end of the rail has an inclined face 1l extending from the rail tread to a horizontal base-face l2 which is parallel with the bottom of the rail. The face l1 increases in width from the bottom to the top thereof, and the base-face l2 increases in width from its outer end to its inner end, or to its juncture with the face 11. Such shape of the faces ll and l2 conforms with the shape of the scarf faces 4l and 6. Flanges 13 project upwardly at each side of the face l2 and for a portion of the face 11, so as to form a socket for the scarf. These flanges each have an inclined edge-face lll, and the inner face of each iange is shaped to conform with the shape of the sides of the scarf, so that the socket widens from its deepest point to the flange ends at the face 1l, and increases in width vertically from said deepest point to the top of the flanges. The flanges are provided with a hole lila for the bolt l0, and a space l5 is left between the top of the flanges 13 and the flanges 9, to provide a clearance in fitting the rail joint ends together.

In coupling or oining the rails, the socket rail is lirst secured to the ties, the scarf end of the next rail is placed in position with the face a resting on the face ll and the face 7 resting on the flange faces l-ZL, and from this position the rail is slid upon said faces for wedging the scarf into the socket, and the bolt is inserted.

It will be observed that the inclined faces co-act to form a bearing during the assembling of the rails in track construction; that the scarf is wedged into the socket by a downward movement of the rail, not toward the length of the socket-rail, but in the opposite direction, so that pressure or weight on the rail tread will tend to tighten the joint; and that the slot 9, and the clearance space l5 permits sufficient movement of the rails for tightening the joint.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

l. The combination, with railway rails having inclined end faces, of a diamond shaped scarf depending from one end of the rails and diminishing in thickness lengthwise and inwardly from one of said faces to the rail, flanges extending from the other of said faces and havmg edges inclined parallel with said faces and forming a socket, and means for securing the scarf in the socket.

2. The combination, -with a railway rail having an inclined end face, diminishing in width from the rail tread to the base of the rail, and flanges projecting from the sides of the said face and having edges inclined from the rail-base parallel with said face and forming a socket, of a meeting rail having an y inclined end face, a scarf, one end of which is formed by this end face, such scarf increasing in thickness from the rail to its said face, and means for securing the scarf in the socket.

ln witness whereof I hereunto set my hand in the presence of two witnesses.
